FIELD

The present disclosure relates to air and water barrier articles androlls thereof The present disclosure also is related to films andbuilding envelopes made using these air and water barrier articles.

BACKGROUND

Air barrier systems control movement of air, and specifically watervapor, across a surface of a structure, such as a building enclosure. Inexterior walls, uncontrolled air flow is the greatest source of moistureand condensation damage. Indoor comfort is affected by air temperature,relative humidity, direction of airflow and surrounding surfacetemperatures. Indoor air quality is enhanced by air barrier systems byefficiently keeping pollutants out of building interiors. Pollutantsinclude water vapor, suspended particulates, dust, insects, smells, etc.Air barrier systems have significant impact on electricity consumptionand gas bills. Air barrier systems in nonresidential buildings areestimated to reduce air leakage by up to 83 percent, reduce heatingbills more than 40% and reduce electricity consumption more than 25%according to simulations by the National Institute of Standards andTechnology (NIST) compared to typical buildings without air barriers.Water vapor is a key ingredient in corrosion and mold growth. Airbarrier systems help prevent water vapor from being transported by airmovement between exteriors and interiors of structures, such asbuildings.

The use of air barrier systems has been a requirement in Canada foralmost 25 years and is becoming important in North America due to netzero energy requirements by 2030, required by the U.S. Army Corp ofEngineering, ASHRAE 90, and International Energy Conservation Code—2009.On Dec. 16, 2011, the DC Construction Codes Coordinating Board (CCCB)adopted the 2012 International Energy Conservation Code (IECC).

Previously known waterproofing sheets having both waterproofing propertyand moisture permeability have been developed. One typical example ofsuch moisture-permeable waterproofing sheets is flash-spun fabrics. U.S.Pat. No. 3,169,899, for example, discloses a flash-spun fabric. U.S.Pat. No. 3,532,589 discloses a method for producing a flash-spun fabric.The fabric thus obtained has an appropriate pore size. It blocks water,but allows water vapor to pass therethrough. A known example of thefabric is commercially available under the trade designation “Tyvek”from E. I. Du Pont de Nemours and Company, Wilmington, Del. USA obtainedby thermo-compressing a three-dimensionally-meshed fiber of high-densitypolyethylene. Such a moisture-permeable waterproofing sheet can preventexternal water from infiltrating through the sheet, but can draingathered moisture as water vapor.

However, the openings such as windows or doors are not flat. It isdifficult to form a waterproofing layer only with a waterproofing sheet,and therefore the opening is often finished with a waterproofing tapewith a pressure sensitive adhesive layer provided thereon. In this case,since the pressure sensitive adhesive layer is made of rubber or asphaltmaterials, the moisture permeability of the entire tape decreases, andthe same problem as that of a common waterproofing sheet can occur.

Mechanical fasteners or adhesive fasteners, such as pressure sensitiveadhesive tapes, can be used to affix the moisture-permeablewaterproofing sheet on substrates of exterior walls or to affixoverlapped portions of two moisture-permeable waterproofing sheets. As aresult, moisture may permeate from gaps of such fasteners, such as nailholes or pressure sensitive adhesive tapes, over a long period of time.It is beneficial for such moisture-permeable waterproofing sheets topass ASTM D-1970/D-1970M-13 or similar modified tests such as ModifiedTest 1 of ASTM D-1970/D-1970M-13, Modified Test 2 of ASTMD-1970/D-1970M-13, or Modified Test 3 of ASTM D-1970/D-1970M-14 for nailsealability. It is also beneficial to provide easy application of theair and water barrier article to substrates, such as buildingcomponents, by not having to remove the release liner before or duringapplication. However, without low release force on the edge of thepressure sensitive adhesive tape, it can be difficult to initiate theremoval of the liner. It is beneficial to have an easy peel tab.

A (meth) acrylic ester polymer having a reactive silicon group may beadded to the curable composition of the present invention if necessary.A (meth) acrylic ester monomer composing the main chain of theabove-mentioned (meth) acrylic ester polymer is not particularly limitedand various monomers may be used. Examples thereof include (meth)acrylic ester monomers such as methyl (meth) acrylate, ethyl (meth)acrylate, n-propyl (meth) acrylate, isopropyl (meth) acrylate, n-butyl(meth) acrylate, isobutyl (meth) acrylate, t-butyl (meth) acrylate,n-pentyl (meth) acrylate, n-hexyl (meth) acrylate, cyclohexyl (meth)acrylate, n-heptyl (meth) acrylate, n-octyl (meth) acrylate,2-ethylhexyl (meth) acrylate, nonyl (meth) acrylate, decyl (meth)acrylate, dodecyl (meth) acrylate, phenyl (meth) acrylate, tolyl (meth)acrylate, benzyl (meth) acrylate, 2-methoxyethyl (meth) acrylate,3-methoxybutyl (meth) acrylate, 2-hydroxyethyl (meth) acrylate,2-hydroxypropyl (meth) acrylate, stearyl (meth) acrylate, glycidyl(meth) acrylate, 2-aminoethyl (meth) acrylate,gamma-(methacryloyloxypropyl) trimethoxysilane,gamma-(methacryloyloxypropyl) dime thoxymethylsilane,methacryloyloxymethyltrimethoxysilane,methacryloyloxymethyltriethoxysilane, methacryloyloxymethyldimethoxymethylsilane, methacryloyloxyme thyldiethoxymethylsilane,ethylene oxide adduct of (meth) acrylic acid, trifluoromethylmethyl(meth) acrylate, 2-trifluoromethylethyl (meth) acrylate,2-perfluoroethylethyl (meth) acrylate,2-perfluoroethyl-2-perfluorobutylethyl (meth) acrylate, perfluoroethyl(meth) acrylate, trifluoromethyl (meth) acrylate, bis (trifluoromethyl)methyl (meth) acrylate, 2-trifluoromethyl-2-perfluoroethylethyl (meth)acrylate, 2-perfluorohexylethyl (meth) acrylate, 2-perfluorodecylethyl(meth) acrylate, and 2-perfluorohexadecylethyl (meth) acrylate.

With respect to the (meth) acrylic ester polymer, the following vinylmonomers can be copolymerized together with a (meth) acrylic estermonomer. Examples of the vinyl monomer are styrene monomers such asstyrene, vinyltoluene, alpha-methylstyrene, chlorostyrene,styrenesulfonic acid and its salts; fluorine-containing vinyl monomerssuch as perfluoroethylene, perfluoropropylene, and vinylidene fluoride;silicon-containing vinyl monomers such as vinyltrimethoxysilane andvinyltriethoxysilane; maleic anhydride, maleic acid, and monoalkyl anddialkyl esters of maleic acid; fumaric acid, and monoalkyl and dialkylesters of fumaric acid; maleimide monomers such as maleimide,methylmaleimide, ethylmaleimide, propylmaleimide, butylmaleimide,hexylmaleimide, octylmaleimide, dodecylmaleimide, stearylmaleimide,phenylmaleimide, and cyclohexylmaleimide; nitrile group-containing vinylmonomers such as acrylonitrile and methacrylonitrile; amidogroup-containing vinyl monomers such as acrylamide and methacrylamide;vinyl esters such as vinyl acetate, vinyl propionate, vinyl pivalate,vinyl benzoate, and vinyl cinnamate; alkenes such as ethylene andpropylene; conjugated dienes such as butadiene and isoprene; and vinylchloride, vinylidene chloride, allyl chloride, and allyl alcohol. Theymay be used alone or a plurality of them may be copolymerized. Of them,in terms of properties such as the physical properties of a producedmaterial, polymers comprising a styrene monomer and/or a (meth) acrylicacid monomer are desirable. (Meth) acrylic ester polymers comprisingacrylic ester monomers and/or a methacrylic ester monomer are moredesirable and acrylic ester polymers comprising acrylic ester monomersare further desirable. In the present disclosure, these desirablemonomers may be copolymerized with other monomers and alsoblock-copolymerized with them. In that case, these desirable monomersare desirably contained at a ratio of 40% by weight or higher. In theabove descriptions, (meth) acrylic acid means acrylic acid and/ormethacrylic acid.

A synthesis method of the (meth) acrylic ester polymer is notparticularly limited and a conventionally known method may be employed.A polymer obtained by a common free radical polymerization method usingan azo compound, a peroxide or the like as a polymerization initiatorhas a problem that the molecular weight distribution value is generallyas high as 2 or higher and the viscosity is thus high. Accordingly, aliving radical polymerization method is desirably employed in order toobtain a (meth) acrylic ester polymer having narrow molecular weightdistribution and low viscosity and having a crosslinkable functionalgroup at a molecular chain end at a high ratio. Of the “living radicalpolymerization methods”, an “atom transfer radical polymerizationmethod” for polymerizing a (meth) acrylic ester monomer using an organichalide, a halogenated sulfonyl compound or the like as an initiator anda transition metal complex as a catalyst has, in addition to thecharacteristics of the above-mentioned “living radical polymerizationmethods”, a wide range of the options of the initiator and the catalystbecause a halogen, etc. which is relatively advantageous for thefunctional group conversion reaction is located at a molecular chainend. The atom transfer radical polymerization method is thereforefurther desirable as a production method of the (meth) acrylic esterpolymer having a specified functional group. Examples of the atomtransfer radical polymerization method are, for example, the methoddisclosed in Krzysztof Matyjaszewski et al., J. Am. Chem. Soc, vol. 117,p. 5614 (1995).

Also, a productionmethod employing an atom transfer radical polymerization method isdisclosed in Japanese Kokai Publication H9-272714 and the like; and themethod is not limited to these exemplified methods. The above-mentioned(meth) acrylic ester polymers having a reactive silicon group may beused alone or two or more kinds of them may be used in combination. Amethod for producing an organic polymer involving blending apolyoxyalkylene polymer having a reactive silicon group with a (meth)acrylic ester polymer having a reactive silicon group is notparticularly limited, and examples thereof include those disclosed inJapanese Kokai Publication S59-122541, S63-11264, H6-172631, andH11-116763.

Pressure Sensitive Adhesive

In some embodiments, the air and water barrier article s areself-adhering, comprising an adhesive material, preferably a pressuresensitive adhesive material, more preferably a solventless or hot meltpressure sensitive adhesive at least partially coated on an outer majorsurface of the article. A removable release sheet or liner mayadvantageously overlay and contact the adhesive in order to prevent theadhesive from adhering to the back side (i.e., non-adhesive coated)major surface of the air and water barrier article in roll form, therebypreventing “blocking” of the rolled air and water barrier article. Therelease liner is removed prior to applying the air and water barrierarticle to an architectural structure. Alternatively, the back sidemajor surface of the air and water barrier article may include anoverlaid or overcoated low surface energy release layer or low adhesionbacksize (LAB); such embodiments are preferably used in linerlessarticles.

Any pressure sensitive adhesive used to adhere air and water barrierarticles to architectural structures (e.g., buildings) may be used.These include both vapor permeable and vapor impermeable pressuresensitive adhesives. An example of the latter is a rubber modifiedasphalt (bitumen) pressure sensitive adhesive or a synthetic rubberpressure sensitive adhesive. Such pressure sensitive adhesives are wellknown in the art.

In some embodiments, the adhesive is selected to be a solventless or hotmelt adhesive. In some embodiments, solvent based adhesives, water basedadhesives may be used. Exemplary types of adhesives include, forexample, radiation-cured, e.g., ultraviolet (UV) radiation orelectron-beam cured (co)polymers resulting from polymerizable monomersor oligomers) may be used. The applied adhesive is preferably tacky(i.e. sticky) and pressure sensitive.

Suitable hot melt adhesives may contain such ingredients as (co)polymerssuch as butyl rubber, styrene-butadiene-styrene (SBS),styrene-isoprene-styrene (SIS), styrene butadiene (SB),styrene-ethylene-butadiene-styrene (SEBS) and ethylene/vinylacetate(EVA); the following passage describes additives commonly used in hotmelt adhesives. They are not typically used as adhesives by themselves.Resins such as those of the hydrocarbon and rosin types hydrocarbons androsins are employed as tackifiers in hot melt adhesives, natural andpetroleum waxes, oil, and bitumen are used as additives, oils, bitumenand others.

Solvent-based adhesives may contain ingredients such as those listedabove, dissolved or dispersed in a solvent vehicle. Water basedadhesives would normally be based on emulsions of (co)polymericmaterials. Suitable (co)polymeric materials include vinyl acetate and(meth)acrylic homopolymers and copolymers the phrase “(meth)acrylichomopolymers and copolymers” is typically used to mean homopolymers andcopolymers of one or more (meth)acrylic esters (and acids) only ,ethylene/vinyl acetate as well as styrene/acrylic, vinylchloride/acrylic, vinyl versatate and others. Water based adhesives mayhave the disadvantage that they generally require the additional use ofdrying ovens or heat lamps to evaporate the water.

If a vapor permeable pressure sensitive adhesive is used, the air andwater barrier article may be completely coated on one side. If a vaporimpermeable pressure sensitive adhesive is used, then the air and waterbarrier article may be only partially coated with adhesive, typically inthe range of about 10% to 90%, more typically about 30% to 80%, mosttypically 40% to 70%, of the surface area of the sheet. In other words,at least 10% to 90%, preferably 30% to 80%, most preferably 40% to 70%,of the surface area of the air and water barrier article should beadhesive-free in order to maintain sufficient vapor permeability of thearticle.

The adhesive may suitably be applied at a thickness of 0.001 inches to0.1 inch (about 0.0254-2.54 mm), but is preferably applied at athickness of 0.003 inches to 0.025 inches (about 0.0762-0.635 mm) andmost preferably at a thickness of 0.005 inches to 0.02 inches (about0.127-0.508 mm).

As noted above, the adhesive may be protected with a strippable releasesheet or liner to enable packaging in rolls. Suitable release sheets arepaper or (co)polymer film sheets with an overlaying, low surface energy(e.g., silicone) release surface coating.

In some embodiments, release sheets or liners useful in the presentdisclosure include those made a using a method for producing an at leastpartially cured layer (optionally a fully cured layer), the methodincluding applying a layer comprising a (meth)acrylate-functionalsiloxane to a surface of a substrate, and irradiating the layer in asubstantially inert atmosphere with a short wavelength polychromaticultraviolet light source having a peak intensity at a wavelength of fromabout 160 (+/−5) nanometers (nm) to about 240 (+/−5) nm to at leastpartially cure the layer. Optionally, the layer is at a curingtemperature greater than 25° C.

Thus, in some exemplary embodiments, the material comprising the layermay be heated to a temperature greater than 25° C. during or subsequentto application of the layer to the substrate. Alternatively, thematerial comprising the layer may be provided at a temperature ofgreater than 25° C., e.g. by heating or cooling the material comprisingthe layer before, during, and/or after application of the layer to thesubstrate. Preferably, the layer is at a temperature of at least 50° C.,60° C. 70° C., 80° C., 90° C., 100° C., 125° C., or even 150° C.Preferably the layer is at a temperature of no more than 250° C., 225°C., 200° C., 190° C., 180° C., 170° C., 160° C., or even 155° C. Releasesheets or liners made using such methods are described in detail in WO2013/032771 A1, the entirety of which is herein incorporated byreference.

Adhesive Patterns

To retain a desired level of water vapor permeance in the air and waterbarrier articles, the adhesive is preferably applied to the air andwater barrier article in a discontinuous manner in order to leave parts,or spots or zones of the major outer surface of the air and waterbarrier article uncoated with adhesive.

In order to prevent the lateral movement of air between the air andwater barrier article and the substrate to which it is bonded, andthrough lap joints of the air and water barrier article, the adhesivecoated areas of the air and water barrier article can be made tointersect to isolate the uncoated areas, thereby eliminating channelsthrough which air can laterally move. This can be achieved by any numberof patterns, such as intersecting circles with adhesive free centers,intersecting squares or rectangles of adhesive, intersecting strips in acheckered pattern, etc.

The adhesive may suitably be applied so as to cover 5% to 99% of thearea of one side of the membrane, but is preferably applied to coverbetween 10% and 90% of the area, and most preferably between 50% and 80%of the area, to obtain the optimum balance of adhesion and vaporpermeance for the sheet.

Partial coatings of adhesive may be applied in a random fashion or in aspecific pattern. Some exemplary partial coatings of adhesive aredescribed, for example, in U.S. Pat. Nos. 3,039,893, 3,426,754,5,374,477, 5,593,771, 5,895,301, 6,495,229, and 6,901,712. In someembodiments, the presently disclosed air and water barrier article has amoisture vapor transmission rate of 1 perms or more according to ASTME96 method. In some embodiments, the presently disclosed air and waterbarrier article has a moisture vapor transmission rate of 5 perms ormore according to ASTM E96 method. In some embodiments, the film has apermeability of greater than 10 perms according to ASTM E 96. In someembodiments, thicknesses of the different layers used in the air andwater barrier article are varied to achieve desired permeability of thearticle.

Adhesion Modifying Zone(s)

In some embodiments, the roll also includes an adhesion modifying zonedisposed between the second major surface of the article and the firstmajor surface of the liner. In some embodiments, the adhesion modifyingzone is used to increase tack or adhesion between the second majorsurface of the article and the first major surface of the liner when inroll form. Examples of materials or surface treatments useful forincrease tack or adhesion between the second major surface of thearticle and the first major surface of the liner include any chemical orphysical surface modifications to any of the second major surface of thearticle, the first major surface of the liner, or both. For example, achemical surface modifier can be used. For example, in these cases, theadhesion modifying zone can be a primer, adhesive, adhesion promoter,and the like.

In some embodiments, the adhesion modifying zone is used to reduce tackor adhesion between the second major surface of the article and thefirst major surface of the liner. Exemplary materials useful to reducetack or adhesion between the second major surface of the article and thefirst major surface of the liner include any inherently non tackymaterials that can provide a barrier layer between the second majorsurface of the article and the first major surface of the liner. Forexample, in these cases the adhesion modifying zone can be inks, releasecoatings, slip coatings, and the like. Inks useful in the presentdisclosure include, but are not limited to, those commercially availableas liquid, white ink, under the trade designation “DT OPAQUE WHITE” fromSun Chemical Corporation, Carlstadt, N.J. and those commerciallyavailable as liquid, red ink, available under the trade designation“SUNSPECTRO SB TRUWEATHER YS RED” from Sun Chemical Corporation,Carlstadt, N.J.

In some embodiments, adhesion modification can be accomplished byselecting a specific liner surface morphology to increase surface areaand physical interlocking of the coating.

In some embodiments, more than one adhesion modifying zone is used inorder to provide different release forces between the liner and the airand water barrier article of the present disclosure. Referring now toFIGS. 4A and 4B, in some embodiments, a first adhesion modifying zone 40and a second adhesion modifying zone are disposed between the liner 25and the air and water barrier article 21. First adhesion modifying zone40 and second adhesion modifying zone 42 can be positioned in variousconfigurations provided that both of them contact liner 25. As shown inFIG. 4A, first and second adhesion modifying zones (40 and 42,respectively) can be positioned next to and adjacent to one anotherbetween the liner 25 and the air and water barrier article 21 to providetwo different release forces between the liner 25 and the air and waterbarrier article 21 when looking at a cross direction cross section of amultilayer article 10 disclosed herein.

As shown in FIG. 4B, in some embodiment, second adhesion modifying zone42 can be positioned adjacent to a portion of first adhesion modifyingzone 40 and on top of a portion of adhesion modifying zone 40. First andsecond adhesion modifying zones (40 and 42, respectively) of thisembodiment are still disposed between the liner 25 and the air and waterbarrier article 21.

As shown in FIG. 5 , when viewing a top plan view of a cross section ofthe multilayer article 10 disclosed in FIGS. 4A and 4B taken along lineA, first adhesion modifying zone 40 extends along one side of thearticle 10 in the machine direction and second adhesion modifying zone42 extends the opposite side of the article 10 in the machine direction.

In some embodiments, such as those shown in FIGS. 4A, 4B and 5 , aparticular ratio of the width in the cross direction of the firstadhesion modifying zone 40 to the width in the cross direction of thesecond adhesion modifying zone 42 is useful in obtaining a desired easeof separation of the liner from the air and water barrier article. Forexample, in some embodiments, useful ratios of the width in the crossdirection of the first adhesion modifying zone 40 to the width in thecross direction of the second adhesion modifying zone 42 ranges from 3:1to 10:1. In some embodiments, useful ratios of the width in the crossdirection of the first adhesion modifying zone 40 to the width in thecross direction of the second adhesion modifying zone 42 include 56:4,26:4, 58:2, and 28:2. For example, the first adhesion modifying zone canhave a width of about 28 inches in the cross direction while thecorresponding second adhesion modifying zone can have a width of 2inches in the cross direction.

In some embodiments, such as those shown in FIGS. 4A, 4B and 5 , it isuseful to control the amount of release force between the first adhesionmodifying zone 40 and the liner 25 versus the amount of release forcebetween the second adhesion modifying zone 42 and the liner. Forexample, in some embodiments, a useful a ratio of a release force of thefirst adhesion modifying zone 40 from the liner 25 to a release force ofthe second adhesion modifying zone 42 from the liner 25 is at least 1:13

Nail sealability of air and water barrier article s was evaluatedgenerally as described in ASTM D-1970/D-1970M-13: “StandardSpecification for Self-Adhering Polymer Modified Bituminous SheetMaterials Used as Steep Roofing Underlayment for Ice Dam Protection”,Paragraph 7.9: “Self Sealability. Head of Water Test” with somemodifications. All materials were conditioned at (23° C. (73° F.)) forat least 24 hours prior to use. Two different modified tests wereemployed. Samples were considered to have passed the test if a rating of“A” or “B” was achieved.

Modified Test 1 of ASTM D-1970/D-1970M-13

A plywood substrate having a thickness of 1.25 cm (0.5 inches) wasemployed; four nails were driven through the air and water barrierarticle into the plywood substrate until 6.35 millimeters (0.25 inches)remained above the exposed surface of the air and water barrier article;and a red dye was added to the water. After exposure the surface ofplywood substrate in contact with the air and water barrier article(referred to herein as the “topside”), and the surface of the plywoodsubstrate opposite the topside (referred to herein as the “bottomside”)were inspected visually by unaided eye for signs of water leakage asdetermined by the presence of red-stained areas around each of the fournails. Such stained areas would be indicative of failure of the air andwater barrier article to form a seal around the nails. Samples wererated “A” if 3 or 4 of the nail areas on the plywood substrate were freeof dye staining; “B” if 2 of the nail areas on the plywood substratewere free of dye staining; and “C” if 1 or 0 of the nail areas on theplywood substrate were free of dye staining.

Modified Test 2 of ASTM D-1970/D-1970M-13

Modified Test 2 was conducted in the same manner as Modified Test 1 withthe following change. The four nails were driven through the air barrierarticle into the plywood substrate until the nail head contacted the topsurface of the air and water barrier article, then the nail was backedout until 6.35 millimeters (0.25 inches) remained above the exposedsurface of the air and water barrier article.

Modified Test 3 of ASTM D-1970/D-1970M-14

Modified Test 3 was conducted in the same manner as Modified Test 2 withthe following change. The nails were not backed out, but left in contactwith the top surface of the air and water barrier article.

Moisture Vapor Transmission

Moisture vapor transmission of air and water barrier article s wasevaluated generally as described in ASTM E96/E96M-13: “Standard TestMethods for Water Vapor Transmission of Materials” using Paragraph 11:Dessicant Method at (23° C. (73° F.)) and 50% relative humidity, withthe following modifications. One specimen was evaluated, with thepressure sensitive adhesive facing into the Petri dish; six data pointswere obtained and used to calculate a permeance value. The sixindividual values were used to determine an average permeance valuewhich was reported in units of Perms.

180° Angle Peel Adhesion Test 1 (Easy Side Release=Adhesive Strength)

The 180 degree peel adhesion strength between the release liner andpattern coated pressure sensitive adhesive, also referred to herein asthe “easy side release”, was measured on a laminate of releaseliner/pattern coated pressure sensitive adhesive/porous layer. Adhesivestrength was measured after aging for seven days at 23° C. and 50%relative humidity. A 2.54 cm wide by approximately 20 cm (1 in. by 8in.) long sample of the laminate was cut using a specimen razor cutter.The exposed release liner surface was attached lengthwise to thepreviously cleaned aluminum platen surface of a peel adhesion tester(Model SP3M90, IMASS Incorporated, Accord, Mass.). The laminate was thenrolled down one time in one direction with a 2 kg (4.4 lb.) rubberroller at a rate of 230 cm/minute (90 in/min.). The pressure sensitiveadhesive/porous layer was carefully lifted away from the release lineradhered to the platen surface, doubled-back at an angle of 180 degrees,and secured to the clamp of the peel adhesion tester. The 180 degreeangle peel adhesion strength was then measured as the pressure sensitiveadhesive/porous layer was peeled from the release liner at a rate of 230cm/min (90 in/min). A minimum of two test specimens were evaluated withresults obtained in ounces (oz)/inch which were used to calculate theaverage release strength. Release testing was conducted under ConditionA described in 180° Angle Peel Adhesion Test 2 (Tight Side Release=LinerRelease) below.

180° Angle Peel Adhesion Test 2 (Tight Side Release =Liner Release)

The 180 degree peel adhesion strength between the release liner andpolymeric material, also referred to herein as the “tight side release”,was measured on a laminate of release liner/polymeric material/porouslayer. The same procedure as described for “180° Angle Peel AdhesionTest 1 (Easy Side Release=Adhesive Strength)” was used with thefollowing modification. The polymeric material/porous layer wascarefully lifted away from the release liner adhered to the platensurface, doubled-back at an angle of 180 degrees, and secured to theclamp of the peel adhesion tester. The 180 degree peel adhesion strengthbetween the release liner and polymeric material was measured after allaging conditions (A, B, and C) given below.

-   -   A) After 7 days at 23° C. (73° F.) and 50% relative humidity        (RH);    -   B) After 7 days at 70° C. (158° F.) followed by equilibration        for 4 hours at 23° C./50% RH;    -   C) After 7 days at 32° C. (90° F.) followed by equilibration for        4 hours at 23° C./50% RH.

EXAMPLES Example 1

An air and water barrier article having a porous layer partiallyimpregnated and covered on one side with a polymeric material and havinga discontinuous pressure sensitive adhesive layer disposed on the sideof the porous layer opposite the side that was coated with the polymericmaterial was prepared as follows. The polymeric material composition wasprovided by charging the following materials into a mixing vessel thatwas then place in a dual asymmetric centrifuge mixer: 39.8 parts byweight (hereinafter abbreviated as “pbw”) of a silyl-terminatedpolyether, KANEKA MS POLYMER S203H, 1.25 pbw of hydrophobic fumedsilica, AEROSIL R202, 26.7 pbw of calcium carbonate OMYACARB 5-FL, and4.4 pbw of titanium oxide, TIONA 696. After mixing at 2500 rpm for fourminutes 0.87 pbw of an aminosilane, DYNASYLAN DAMO-T, 0.87 pbw of avinyl trimethoxysilane, DYNASYLAN VTMO, and 0.19 pbw of a tin catalyst,NEOSTANN U-220H, were added and mixed at 2500 rpm for two minutes. Thisfinal mixture was used to coat a silicone treated, polyethylene-coatedKraft paper using a notch bar coater having a gap setting that was 0.30millimeters (0.012 inches) greater than the thickness of the releasepaper. The coated release paper then laminated to a porous layer, REEMAY2024 polyester, at room temperature (23° C. (73° F.)) using a handroller and negligible pressure. This laminate construction was cured at93° C. (200° F.) for 8 hours. The release paper then was removed to givea partially impregnated air and water barrier article having acontinuous layer of polymeric material on one side of a porous layer,and having an approximate total thickness of 0.33 millimeters (0.0128inches).

A pressure sensitive adhesive composition was prepared by mixing 99parts pbw isooctyl acrylate (IOA), 1 pbw acrylic acid (AA) and 0.04 pbwof a photoinitiator, IRGACURE 651. This mixture was partiallypolymerized under a nitrogen atmosphere by exposure to low intensityultraviolet radiation to provide a coatable syrup having a viscosity ofabout 4000 cps. An additional 0.26 pbw of IRGACURE 651, 0.13 pbw of aTriazine, and 6 pbw of a tackifier, FORAL 85LB, were added to the syrupand mixed until all of the components had completely dissolved to give apressure sensitive adhesive precursor composition. The precursorcomposition was coated at a line speed of 2.74 meters/minute (9feet/minute) onto a silicone treated, polyethylene coated Kraft paperliner.

The pressure sensitive adhesive precursor composition was provided todispensing outlets on both a first distribution manifold and a seconddistribution manifold. The dispensing outlets on the first manifold,spaced 12.5 millimeters (0.5 inches) apart, were reciprocated at a rateof 1.67 Hz and a peak-to-peak amplitude of 12.5 millimeters (0.5 inches)in the width-wise direction of the liner as it moved in its' length-wisedirection, while the dispensing outlets on the second manifold, spaced12.5 millimeters (0.5 inches) apart, were kept stationary.

The coating weight was 0.013 grams/square centimeter (32 grains per a 4inch by 6 inch area). The coated liner was then exposed to ultravioletradiation having a spectral output from 300-400 nm with a maximum at 351nm in a nitrogen-rich environment. An intensity of about 9.0milliWatts/square centimeter was used during the exposure time,resulting in a total energy (dose) of 1800 milliJoules/squarecentimeter.

The result was a pattern of parallel sinusoids of the pressure sensitiveadhesive composition aligned in the longitudinal direction of the paperliner and positioned between the straight line stripes of the pressuresensitive adhesive composition. The sinusoidal patterns contacted thestraight line patterns. The adhesive covered approximately 56% of thearea of the liner surface, with approximately two thirds of that beingattributable to the sinusoidal patterned adhesive and approximately onethird of that being attributable to the straight line patternedadhesive.

For nail sealability evaluation the paper liner containing thepattern-coated pressure sensitive adhesive was transfer laminated usinghand pressure to a 12.7 millimeter (0.5 inch) thick piece of plywoodsubstrate. Next, the air and water barrier article was laminated by handto the plywood substrate such that the porous layer covered thepatterned coated pressure sensitive adhesive layer. This article wasthen evaluated for nail sealability test method 1.

Measurement of water vapor transmission was conducted on a sampleprepared by directly laminating the exposed pressure sensitive adhesivesurface of the pattern-coated pressure sensitive adhesive paper lineronto the non-coated surface of the air and water barrier precursormaterial. This was rolled down by hand using a rubber roller to ensuretransfer of the adhesive onto the air and water barrier precursorarticle to give an air and water barrier article having a pattern coatedpressure sensitive adhesive on one side and a polymeric material coatedon the opposite side. The results are shown in Table 1.
